Detailed Description

template<class T>
class Safir::Dob::Typesystem::ValueContainer< T >

Container for base types.

This class holds a value of the template argument type and a null flag. The operations that modify the value update the null flag and the change flag (which is inherited from ContainerBase).

This container is intended for the simple types of the DOB typesystem. There should be no need to use this type in a definition, since all the relevant instances of this template are defined with typedefs (e.g. Int32Container, BooleanContainer, EntityIdContainer, etc).

Parameters

T	The type to contain.

Member Typedef Documentation

ContainedType

template<class T >

typedef T Safir::Dob::Typesystem::ValueContainer< T >::ContainedType

Constructor & Destructor Documentation

ValueContainer()

template<class T >

constexpr Safir::Dob::Typesystem::ValueContainer< T >::ValueContainer ( )

constexpr

Default constructor.

Creates a null and not changed container.

Member Function Documentation

Copy()

template<class T >

void Safir::Dob::Typesystem::ValueContainer< T >::Copy ( const ContainerBase & that )

overridevirtual

Virtual assignment.

Copy all the members from "that" into "this". Types must be the same for this to work!

Parameters

that	[in] - The object to copy into this.

Exceptions

SoftwareViolationException

If the types are not of the same kind.

Implements Safir::Dob::Typesystem::ContainerBase.

References __WFILE__.

GetVal()

template<class T >

T Safir::Dob::Typesystem::ValueContainer< T >::GetVal

(

)

const

Get the value of the container.

Returns

The value of the container.

Exceptions

NullException

The container is null.

References __WFILE__.

IsNull()

template<class T >

bool Safir::Dob::Typesystem::ValueContainer< T >::IsNull ( ) const

overridevirtual

Is the container set to null?

Returns

True if the container is set to null.

Implements Safir::Dob::Typesystem::ContainerBase.

SetNull()

template<class T >

void Safir::Dob::Typesystem::ValueContainer< T >::SetNull ( )

overridevirtual

Set the container to null.

Implements Safir::Dob::Typesystem::ContainerBase.

References Safir::Dob::Typesystem::ContainerBase::m_bIsChanged.

SetVal()

template<class T >

void Safir::Dob::Typesystem::ValueContainer< T >::SetVal

(

const T

value

)

Set the value of the container.

Null and change flags are updated accordingly.

Parameters

value

[in] - The new value.
